Printing-press



UNITED STATES PATENT OFFICE.

CHARLES MONTAGUE, OF HARTFORD', CONNECTICUT.

PRINTING-PRESS.

Specification of Letters Patent No.

To all whom 'it may concern:

Be it known that I, CHARLES MONTAGUE, of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Printing-Press; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side elevation of my improved printing press, and Fig. 2 is a front elevation of same. Fig. 3 is a view of detached parts.

Like letters designate like parts in all the figures.

The nature of my invention consists in such an arrangement of a horizontal reciprocating bed and revolving cylinder for impression, that the surface of the bed, or form placed upon it, shall always travel in correspondence with the surface of the cylinder; and the cylinder is made to complete its revolution by other means independent of the motion imparted to it by the bed, after the impression is given.

The bed, B, slides horizontally upon suitable ways M M. A reciprocating movement is given to it by means of a vibrating lever, as represented in the drawings, marked D, attached to which is a rod z' z', which is fastened to the bed at the point marked y, for the purpose of imparting the motion of the lever to the bed. Said lever or rocker is made to vibrate by means of a crank a, which is attached to the driving shaft c, and enters a long radial slot'P in the lever. The driving shaft is turned in the proper direction to cause the crank n to act in the upper end of slot P when the bed is moving in the proper direction for taking an impression (as shown by the arrow, Eig. and to act in the lower end of said slot while bringing t-he bed back after each impression.

Upon the shaft F, on which the cylinder A is fastened, are two ratchet-wheels, marked g1 g2, one inside and the other outside of the journal, made to play freely upon said shaft. Upon the inside ratchet wheel or pulley, marked g1, which is made the same size as cylinder A, a cord is passed around, its middle being fastened to the 22,027, dated November 9, 1858.

pulley, and its ends attached to the ends of the projecting slot or bar 7L, on the bed B, as shown in the drawings, through which a vibratory movement is imparted to said pulley by the movements of the bed, as shown in F ig. l.

lVhen the bed B moves forward in the direction shown by the arrow for making an impression, the pulley g1 is drawn around in the direction indicated by the arrow thereon, (Fig. l) and the ratchet-wheel g2 having brought the cylinder in the same direction in a position to allow the click f1 to lock into notch el, the cylinder receives its motion from the bed B, which moving a little faster than the ratchet-wheel g2, carries the cylinder forward a short distance from the notch e2, in the outside ratchet-wheel g2, while the impression is being given, until the bed B has reached the end of its motion, at which point the ratchet-wheel (2 and click f2 overtake the notch 62. The cylinder now receives its motion from the outside ratchet-wheel g2, and while the bed B is making its return movement, the cylinder' is completing its revolution to the .position from which it started as above described.

The sheets are fed to the cylinder from the table, and are delivered from said cylinder by any well known means. The cylinder may be made of a size to be kept in a continual motion, or if smaller, may rest a short space until the motion of the ratchet wheel g2 overtakes the notch e2.

Having thus fully described my improvement in printing presses, what I claim as new, and desire to secure by Letters-Patent 1s- Communicating motion to the cylinder at the time of giving the impression by and through the motion of the bed, while the revolution of the cylinder shall be perfected by or through ordinary gearing or other means entirely independent of the motion of the bed, thus alternating from one of these means to the other to give a full revolution to the cylinder, in the manner substantially as herein setforth.

CHARLES MONTAGUE.
